Well the story certainly isnt worded in a favorable light for law enforcement. Quite simply, the first line of the article (and title of this thread, I might add) is erroneous.
The cops didnt "break in" to anyone's house (no matter how many times that those words get repeated in the article). "Breaking in" to someone's home is illegal. A judge granted these officers a felony search warrant and they executed a felony search warrant. Here in Georgia, this can be a "no knock" or "knock first" warrant. Either way, they were within their rights and protocol to enter the home aggressively to conduct the search.
That said, when I have been a part of teams that execute these warrants, every person, young or old, handicapped or able bodied, male or female, is treated the same. However that does not mean kept on the floor at gun point. They should be searched and secured in a safe area.
Also, I dont know if the dog was acting aggressively or not. If it was, then yes, shooting it is an option to protect the officers. However, this line: They shot him with a shotgun in such a manner that he ran around in pain and bled all over the house and suffered a slow, cruel death is one of the most ridiculous I have ever seen in print. It makes it sound like the officers shot him only to injure him and make him suffer for their own cruel purposes.
Now before anyone attacks me, if this happened 100% the way that the lady claims, then the police made several mistakes that should be dealt with (not identifying themselves, keeping her in a hot car, etc etc). I am simply pointing out that the article is erroneous about some of the wording and seems to paint this entire thing off as police just being ***** for the fun of it and not there doing their job.
